These pumps are mainly used in situations where, by law, discharge must be realized "overhead". The configuration of the SLM SV allows the gas flow to be transported along with the fluid. The pump can also achieve low NPSH values if an upstream centrifugal stage is realized.

Heated pump H5 and/or H2The pumps are outfitted with a heat jacket and pump casing (H5) and/or a heat jacket in the bearing lantern (H2). Both heat jackets can be realized either separately or in conjunction with a bypass line. The heat jackets in the standard construction are rated for operating pressure of 16 bar at 200 Â°C (steam) or 6 bar at 350 Â°C. The heat jackets can also be used for cooling.

S or W thermal barrier and secondary seal The thermal barrier acts as a structural element between the bearing carrier (in the bearing carrier model) or drive motor (in the close coupled model), whereas the hydraulic system allows for heat transfer. This reduces ball bearing temperatures in the gearing when hot liquids are being transported. A radial shaft sealing ring can also be integrated into the thermal barrier for purposes of sealing the magnet driver. The sealing ring acts as a secondary seal that prevents the product from leaking into the environment through a leak in the isolation shell. In order for this secondary seal to be used, the magnet driver chamber must be monitored so that leaks can be detected in good time.

Double isolation shell DThe double isolation shell should be used in situations requiring a high level of safety. The unit consists of two interlocking isolation shells, both of which are rated for the relevant operating conditions. If one of the two units is damaged, the casing still remains leaktight. The gap between the two units can be monitored.
